Superman can fly around the world so fast he can reverse time. But in Superman comics this year, Kal-El will be hoofing it from sea to shining sea to reconnect with Americans. And he might stop by your hometown!

DC Comics' Source blog revealed today that in J. Michael Straczynski upcoming "Grounded" story arc, Superman will be taking the low road and trudging across the purple mountain majesties:

Starting in July 2010, coinciding with the 700th issue of Superman, DC Comics will be celebrating this remarkable anniversary of America's greatest hero with a historic journey…not to alien worlds or distant galaxies, but through the streets, roads, highways, homes, farms, suburbs, and inner cities of America. [...] And America itself, in the person of those very real places, is invited to the party.

Beginning with the city of Philadelphia, Superman will walk across America, a journey that is expected to take most of a year. He will pass through Illinois, Iowa, Nebraska, Colorado, Utah, Nevada, California, Oregon and Washington. Along the way, Superman will be passing through real towns, real cities, real neighborhoods.

And your town, your city, your neighborhood may be among those chosen for his historic journey. Superman will literally pass through your town as visualized in the pages of his book. [...] If your town is within 50 miles of the line marking Superman's journey, then you are eligible to participate.

You can read the nitty-gritty of the eligibility requirements at the Source, but basically entrants are required to write an essay explaining why Superman should stop by their towns, which must be within 50 miles of the following cities:
